I will give an example of the distribution of interrupt network interfaces on the processor cores.
For example, I’ll take a server with accel-ppp, 6Gb/s traffic, 500K + pps, nat with ipoe and 6000 dchp clients.
Also, be sure to disable hyper-threading in the BIOS, since load balancing on virtual cores can greatly increase the load on some physical cores.
Cisco 6509e Net Input CPU Load
Once on a single Cisco 6509e switch configured as L3 and with a standard CPU load of 10%, the load suddenly increased to 40%.
